    Answer: They are equivalent, and x = - 4/7

    Step-by-step explanation:

    Fist we need to see what the answers to each of these equations are

    7 + 5x = 3 - 2x

    Subtract 7 on each side

    5x = - 4 - 2x

    Add 2x

    7x = - 4

    X = - 4/7

    Now the second one

    7 + 7x = 3

    Subtract 7

    7x = - 4

    X = - 4/7

    They are equal and x = - 4/7
